• Insert rows in the PL/SQl table

  Hello
  I have a PL/SQl table that I filled through bulk collect and now I'm trying to loop through the table (actually quite a few nested loops)... Now in one of my curls, I might need to insert a new row by splitting the field in the existing row in the table. Can I insert the line in the pl/sql table in the loop without affecting the "FOR i IN tab.first... Tab.Last' loop?
  Also, what would be the index of such a line inserted into the table. Can I access it with tab.last + 1 (doesn't look like it can be done if I insert into various levels of loops).
  OR
  If I insert the lines insde loops nested, then I can access the new lines as soon as I close all the loops and open a new loop? The new lines will be at the last table.
  
  Any help will be appreciated...

  The expression v_arr. LAST gives the index of the last entry, so you can refer to this element as

  v_arr(v_arr.LAST)
  

  Then the attributes of this element will be

  v_arr(v_arr.LAST).attr
  

  for example

  DECLARE
      TYPE table_defs_tt IS TABLE OF user_tables%ROWTYPE INDEX BY PLS_INTEGER;
      v_mytables table_defs_tt;
  BEGIN
      SELECT * BULK COLLECT INTO v_mytables
      FROM   user_tables
      WHERE  ROWNUM <= 100;
  
      DBMS_OUTPUT.PUT_LINE(v_mytables(v_mytables.LAST).table_name);
  END;
  

• How to remove duplicates from the PL - SQL table?

  Hi gurus,
  
  I have a PL - SQL table with the following structure
  Authors (SR_NO, Auth_Code, Change_Date, cost)
  
  This table is filled using a slider. However, this table can have a few lines in double (for column (Auth_Code)
  for example

  SR_NO      Auth_Code       Change_Date                       Cost
  1               A1             14-FEB-09 08.18.47 AM          11.00
  2               A2             14-FEB-09 08.18.56 AM       2839.00
  3               A1             15-FEB-09 08.00.02 AM      1299.00
  4               A1             15-FEB-09 07.00.00 AM        789.00
  5               A3             14-FEB-09 08.18.56 AM        312.00
  6               A4             14-FEB-09 08.19.02 AM        233.00

  I need to get the above result set select the separate lines of Auth_Code including the Change_Date is maximum (and store in another PL - SQL table for treatment later or even the removal of this table will be also!)
  
  of the data A1 is duplicated and a maximum Change_Date above = 15 February 09 08.00.02 AM.
  Where my PL - SQL Table that results must have given below
  

  SR_NO      Auth_Code       Change_Date                       Cost
  2               A2             14-FEB-09 08.18.56 AM       2839.00
  3               A1             15-FEB-09 08.00.02 AM      1299.00
  5               A3             14-FEB-09 08.18.56 AM        312.00
  6               A4             14-FEB-09 08.19.02 AM        233.00

  I'm not very aware of the PL - SQL tables and there is no chance to change the existing cursor that fills the data in this table PL - SQL.
  I guess that I need to compare each record of PL - SQL table with others, but do not know how to do this.

• Select DataSet from the pl/sql table

  Hi Experts,

  I need to create a metric of OEM 12 c extensions. I must create a pl/sql code that can return results to OEM.

  The following code works in OEM. But the problem is that I need to create a permanent table for this case.

  Could you please tell any other option available to do this without creating additional objects at the database level?

  Based on the requirement of the OEM, the end of the script, I have to do something like ' open: 1 to select in the <>' to return the results in a table.

• Using the PL - SQL CAST function

  Hi friends,

  I write a stored procedure that attempts to convert a string returned by a function in a fixed-size varchar (3).

  
  

  ex:

  newChar varchar (3);

  
  

  newChar: = cast (fn_getValue (aInputValue) as varchar (3));

  This is the return type of the function ( fn_getValue) is varchar2 (4000), I should keep the return type as varchar2 because size should vary according to the entry.

  When I run the procedure gives:

  PLS-00103: encountered the symbol "(" quand attend une deles de valeurs suivantes:) "

  . ) @ %

  Please, help me to meet my needs.

  Thanks for your reply...

  It is a generic function and the 3 I've mentioned is just an example, it can change on different cases.

  I tried with select cast (fn_getValue as varchar (aInputValue) (3)) in the double newChar; his work...

  In general, Yes, if the function is a function table, you can do something like:

  select  t.col1,
          t.col2,

          f.col2,

  What happens if the PL/SQL table has NULL values. Question is how you want to handle NULL values. You want to ignore nulls as GROUP BY do? If you want to consider NULL values, you can say if you want to order the NULLS FIRST or NULLS LAST. I guess that logical GROUP BY:

• PL/SQL tables

  Hello guys,.
  I have a few questions about the PL/SQL tables
  
  (1) if I don't specify the 'INDEX BY' clause, they are indexed by PLS_INTEGER default, right?
  
  (2) consider this package specification
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  So I created a table (I hope it's standard indexed by type of data pls_integer) and I am in him passing as parameter to a procedure. Because I want this parameter be optional I assign null inside.
  
  Now, I change the table definition for:
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  Try to compile it and you get:
  Error (5.53): PLS-00382: expression is of the wrong type
  
  Why?
  
  (3) because I need this optional parameter, I use the first statement:
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  Now I create an anonymous block, and you want to set something in the table
  

  DECLARE
     vtab_Numbers TESTXYZ.tab_Numbers;
  BEGIN
  
     vtab_Numbers(1) := 5;
  
  
  END;
  /

  When you try to run it, I got:
  06531 00000 - 'refers to an uninitialized collection.
  
  Can someone help me understand this problem?
  Is it possible to have input of type PL/SQL table setting and have a standard null, are assigned?
  
  Thanks, Dan

  (1) if I don't specify the 'INDEX BY' clause, they are indexed by PLS_INTEGER default, right?

  N ° or somehow.

  More critical, and using official terms of [url http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/composites.htm#CHDBHJEI] documentation so that we don't get into unnecessary arguments about the correct terms for these features, it's the difference between types of ASSOCIATIVE TABLE and the IMBRIQUEE TABLE collection.

  If you omit the "INDEX BY" clause, it is a type of TABLE IMBRIQUEE collection. A type of TABLE IMBRIQUEE is always indexed by PLS_INTEGER.

  When you include the ' INDEX OF ', this is an ASSOCIATIVE ARRAY.

  (2) consider this package specification
  Try to compile it and you get:
  Error (5.53): PLS-00382: expression is of the wrong type

  Why?

  Because you cannot assign NULL to an ASSOCIATIVE ARRAY.

  In the same way, you cannot do this:

  SQL> DECLARE
    2   TYPE tab_Numbers IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
    3   v1 tab_Numbers;
    4  BEGIN
    5   v1 := NULL;
    6  END;
    7  /
   v1 := NULL;

  PLS-00382: expression is of wrong type
  ORA-06550: line 5, column 2:
  PL/SQL: Statement ignored
  
  SQL> 
  

  If you want two entry points to TestNumber with an ASSOCIATIVE ARRAY or NULL then overload the procedure.

  If you want to call a procedure with a TABLE IMBRIQUE collection type you can the default empty:

  SQL> CREATE OR REPLACE PACKAGE Testxyz
    2  AS
    3   TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
    4   PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers DEFAULT tab_Numbers());
    5   PROCEDURE TestNumber;
    6  END Testxyz;
    7  /
  
  Package created.

  (3) because I need this optional parameter, I use the first statement
  When you try to run it, I got:
  06531 00000 - 'refers to an uninitialized collection.

  Because you have not initialized it.

  Different collection types require different semantics.

  Hi all
  
  Newbie when it comes to PL/SQL tables...
  
  Can someone explain to me why it works and how exactly I can do the following without triggering an error?
  
  I have a function that accepts a PL/SQL table like in parameter.
  
  The PL/SQL table is defined as...
  

  Type TTimeTable is table of xxtzg_otl_iface_stg%rowtype index by binary_integer;

  the xxtzg_otl_iface_stg table has many columns including error_message and error_flag. If I find an error, I want to update the error_message and error_flag function. If I can get it works I will then modify the function to return to the table of PL/SQL instead of BOOLEAN
  

  FUNCTION validate_timecard (pTimeTable IN TTimeTable
                                               ) RETURN BOOLEAN IS
  
    lc_module            CONSTANT VARCHAR2(25)        := 'validate_timecard';
    lEmployeeCount    PLS_INTEGER;
    lEmployeeError     VARCHAR2(1000);
    lErrorCount          PLS_INTEGER :=0;
    
    BEGIN
  
       FOR i IN 1 .. NVL(pTimeTable.COUNT,0) LOOP                                   
                                           
       xxtzg_concurrent_utils_pkg.write_log(  p_package =>  gc_package
                                                              , p_module  =>  lc_module
                                                              , p_text    =>  'Processing timecard for employee_number: '||pTimeTable(1).employee_number
                                                             );               
     
       -- Call validations before submitting the timecard to the API
       --validate employee
  
          begin
             select count(*)
               into lEmployeeCount
               from per_all_people_f
              where employee_number = pTimeTable(1).employee_number;
              
              if lEmployeeCount = 0 then
              
              -- Set the errors
  
              -- This assignment below does not work, I get an error message saying...
              --[Error] PLS-00363 (137: 27): PLS-00363: expression 'PTIMETABLE.ERROR_MESSAGE' cannot be used as an assignment target
  
              PTimeTable(i).error_message :=  'Employee Number '||pTimeTable(1).employee_number||' is not a valid employee';
              PTimeTable(i).error_flag := 'Y';
  
              end if;
              
          end;    
          
       END LOOP; 
       
       IF lErrorCount = 0 THEN 
       RETURN TRUE;
       ELSE
       RETURN FALSE;
       END IF;
                                             
    END;

  Your table is declared as IN only (the default if you do not explicitly set it), so you are not allowed to change its attributes in all respects, IN = read-only.

  If you want to be able to modify the values of a parameter, it must be declared as OUT parameters.

• parallel in pipeline table function

  Hi all
  
  To "allow the parallel pipeline" table function, what I need to turn a query parallel session first?
  
  I read a few white papers or web pages on map and reduce implemented with function table Oracle and see that, based on the table.
  
  Use the cursor in the loop to get a line, run out! This replaces SQL pl/sql.
  
  What is the cost that must be paid according to the table?
  
  Finally, how can I confirm that Oracle has put the table function in parallel?
  
  Best regards
  
  Leon

  In my application, I wrote stored procedures that return a collection of user-not of the types of objects to Java.

  Flawed approach using memory expensive private server (PL/SQL PGA) caching SQL data and then push this data to the client - when the customer can use instead the more scalable and higher shared cache buffer memory instead.

  With the types of objects, we can remove most of the redundent data.

  This statement makes no sense that it is the same for SQL and sliders. And remove redundant data is preferable to the SQL itself - through partitioning engine pruning, predicates, only by selecting the columns there is place for the projection of SQL and so on.

  This OO design reduces the load on the network and makes it easy for Java to parse.

  Incorrect answer. It does not reduce network load - it can actually increase. Regarding Java 'parsing' - it's wrong from the beginning approach if the customer is required to analyze the data it receives from the server database. The analysis requires time CPU. Many average general processor muscle which will degrade the performance of analysis.

  You may be using the analysis out of context here? Find it me hard to believe that one could design an application and use a server database in this way. The analysis of means for example to receive XML data (text) and then he analysis in an object - like structure for use.

  Data of the database must be recovered by the customer in a binary structured format and not in a free format that requires the client to analyze in a structured format.

  But the problem is that we accumulate all data in memory first and push them to the client as a whole. If it's too huge, ORA-22813 occurs.
  This is why I intend to use the table of piplelined function.

  How that will solve the problem?

  As I followed your logic:
  (1) you do not use the cursor for some obscure (and probably completely unjustified) reason.
  (2) you may not return large collection PL/SQL variables without significantly dent PGA (process private memory) on the server and running into errors (this approach is conceptually incorrect anyway)
  (3) you are now using an array of pipeline that executes PL/SQL code to execute SQL code - and in turn must be executed by the client as a SQL using a slider

  So why put all the other moving parts (the pipeline code) between the two when the customer
  (a) must use SQL to access?
  (b) create a cursor?

  If, as you say, I returned a cursor, it would be very difficult for Java organize data.

  A table of pipeline must be able to be used through a cursor. All the DML statements from a client by Oracle are analyzed as cursors.

  Read the language PL/SQL Oracle® Database reference guide section on ' + chaining Pipelined Table Functions for Multiple Transformation + ".

  The format using a pipeline is (from the manual):

  SELECT * FROM TABLE(table_function_name(parameter_list))
  

  The "+ pipeline + ' is created by the SQL engine-, he need SQL to execute the PL/SQL code via the function TABLE() SQL.

  You said that the reason to use a pipeline transforms a structure of relational data stored in a structure of the object. You don't need a pipeline for it. Plain vanilla SQL can do the same thing, without the fixed costs of use PL/SQ, SQL data recovery and change within the pipeline between PL/SQL and SQL context engines.

  You simply call the constructor of the class of object in the projection of SQL and the cursor SQL returning the instantiated objects. For example

  create or replace type TEmployee is object(
   .. property definitions ...
  );
  
  create or replace type TEmployeeCollection is table of TEmployee;
  
  select
    TEmployee( col1, col2, .., coln ) as EMP_COLLECTION
  from emp
  where dept_id = :0
  and salary > :1
  and date_employed >= :2
  order by
    salary, date_employed
  

  No need for PL/SQL code. No need for a pipeline. The client will open the cursor and extraction of objects in a collection. The same approach that the customer would have used during extraction of a cursor on a table of pipeline function.

  Pipelines are best used as a process of transformation of data where only SQL cannot perform the transformation. I never in many years of design and writing applications used Oracle PL/SQL pipeline into production on a SQL table. Simply because the SQL itself is capable and powerful enough to do the job - and do it faster and better.

  I used pipeline is to transform the data from external sources into sets of SQL data. For example, a pipe on a web service. When the code PL/SQL of the constructions of the SOAP envelope, the HTTP call, analyzes the XML and returns the content in form of lines and columns - that allows to run a SQL SELECT on web-service-turned-into-a-SQL-table.

  If you'd told me that Leon - it seems to me that your approach is a typical approach to Java that has very little understanding of the concepts of database and Oracle databases. You can't deal with Oracle as a simple persistence layer. You can't treat SQL and PL/SQL as a simple i/o interface for the extraction of data from Oracle and grinding that in Java. Not if you think that your system to run Java and scaling.

  Rethink the Oracle layer, use properly - and your application will occur and will scale. Guaranteed.

  However, from my experience, many J2EE developers choose to treat the Oracle as a black box, not further that a kind of file system loaded to store structured data and try to do it in the Java layer. And this fail. And I saw him failing - of the jaw dropping kind epic failures (knocking all the national newspapers and media as a result and an impact on ordinary people who have to deal with the Government).

  And it's a shame... SQL and PL/SQL are superior to Java in this regard and are the layers much more able to cope and a power of data in the database. Example of the real world - largest table in our busiest database develops between 350 and 450 million lines per day and all our calculations of the data in this table is inside the database layer - and not in a layer of Java. Oracle performs and scales beautifully... when used correctly.

• Performance issue Bulk Insert PL/SQL table type

  Hi all
  
  I put in work of a batch to fill a table with a large number of data records(>3,000,000). To reduce the execution time, I used PL/SQL tables to temporarily store data that must be written to the destination table. Once all documents are piling up in the PL/SQL table I use a FORALL operator for bulk insert the records in the physical table.
  
  Currently, I follow two approaches to implement the process described above. (Please see the code segments below). I need to choose how to best wise performance between these two approaches. I really appreciate all the comments of experts about the runtime of the two approaches.
  
  (I don't see much difference in consumption of time in my test environment that has limited the data series. This process involves building a complex set of structures of large product once deployed in the production environment).
  
  
  Approach I:_
  DECLARE
  TYPE of test_type IS test_tab % ROWTYPE directory INDEX TABLE;
  test_type_ test_type.
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  test_type_ (ins_idx_) .column1: = value1;
  test_type_ (ins_idx_) .column2: = value2;
  test_type_ (ins_idx_) .column3: = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  I_ FORALL in 1.test_type_. COUNTY
  INSERT INTO test_tab VALUES (i_) test_type_;
  END;
  /
  
  
  Approach II:_
  DECLARE
  Column1 IS a TABLE OF TYPE test_tab.column1%TYPE INDEX DIRECTORY.
  Column2 IS a TABLE OF TYPE test_tab.column2%TYPE INDEX DIRECTORY.
  Column3 IS a TABLE OF TYPE test_tab.column3%TYPE INDEX DIRECTORY.
  column1 column1_;
  column2_ Column2;
  column3_ Column3;
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  column1_ (ins_idx_): = value1;
  column2_ (ins_idx_): = value2;
  column3_ (ins_idx_): = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  FORALL idx_ in 1.column1_. COUNTY
  INSERT
  IN n_part_cost_bucket_tab)
  Column1,
  Column2,
  Column3)
  VALUES)
  column1_ (idx_),
  column2_ (idx_),
  column3_ (idx_));
  END;
  /
  
  Best regards

  Performance is more than just reducing the execution time.

  Just as smashing a car stops more than a car in the fastest possible time.

  If it was (breaking a car stopping all simply), then a brick with reinforced concrete wall construction, would have been the perfect way to stop all types of all sorts of speed motor vehicles.

  Only problem (well more than one actually) is that stop a vehicle in this way is bad for the car, the engine, the driver, passengers and any other content inside.

  And pushing 3 million records in a PL/SQL 'table' (btw, that is a WRONG terminology - there no PL/SQL table structure) in order to run a SQL cursor INSERT 3 million times, to reduce the execution times, is no different than using a brick wall to stop a car.

  Both approaches are pretty well imperfect. Both places an unreasonable demand on the memory of the PGA. Both are still row-by-row (aka slow-by-slow) treatment.
